What will be the programming for Abundant Number? 

Today topic is Abundant Number. we will discuss about, what is Abundant Number, what are the examples of Abundant Number, and its programming stuff with program, logic, some output either number is Abundant Number or not.

What is Abundant Number?

Abundant Number are same as Perfect Number but there is slit difference, that a number is Abundant Number when it factor sum or divisor sum is greater then the number, means when we find factor or divisor then the sum of all divisor or factor except that number is greater then that number it is called Abundant Number.

Example:- Let us take a number 30 when we find its divisor we will get 1, 2, 3, 5, 6, 10, 15, 30. But we will not include 30, so sum is :-
1 + 2 + 3 + 5 + 6 + 10 + 15 = 42 which is greater then the original number, so 30 is Abundant Number. 
Let take another number 29 when we will find its divisor  we will get 1, 29, and we have to not include 29 so sum will be  :- 1 which is not equal to the original number, so it is not Abundant Number.


Programming :- 

#include<stdio.h>
#include<conio.h>
int main()
{
int num, i, newNum = 0;    //Data type deceleration.
printf(" Enter the number to check either it is Abundant number  or not");
scanf("%d",&num);  //User input.
for(i=1; i<num; i++)    //For finding divisor.
{
if(num%i==0)      //Condition for divisor 
{
newNum = newNum + i;    //Adding divisor 
}
}
if(newNum > num)    //Comparing the new number to original Number.
{
printf(" %d is a Abundant Number ",num);
}
else
{
printf(" %d is not a Abundant Number ",num);
}
getch();
return 0;
}

Output:-

Output of Abundant Number

Fig:- 1

Output of Non- Abundant Number

Fig:- 2

Logic:-
For Abundant Number we have to look at the logic of the Perfect Number, both have the same logic but difference is at only comparing the new number with the original number. We have to firstly find the divisor of the given number by using For loop and if else condition. After that we have to add all the number excluding the number itself, now we have to compare both number new number and original number and if new number is greater then the original number that that number is Abundant Number other wiser not.

What will be the programming of Automorphic Number? Today we are going to learn about the  Automorphic Number .  We will learn definition , some example, programming and logic behind the  Automorphic Number   and also look at the output either input number is  Automorphic Number   or not. What is Automorphic Number? Automorphic Number is a such type of mathematical number whose square end is equal to the original number. Means if you square the number then the end of that number is equal to original number. Example:- Lets take 5. Then square of it is 25 and this numbers ends with 5 , and last number is equal to original number. Another example 7. Then the square of this number is 49 and end number is 9, which is not equal to the original number. Programming :- #include<stdio.h> #include<conio.h> #include<math.h> int main() { int num, temp,sqrNum, count,last,temp1;    //Data type decelaration printf( "Enter the numb...

What will be the general solution of given star patter in C programming language. This program is executed on Dev C++ editor. You may use any other editor the program will be same. If you face any problem then comment. 1st way #include<stdio.h> #include<conio.h> int main() { int row ,col, n;                                              //Data type declaration printf("Enter the number of rows"); scanf("%d",&n);                                        // Taking user input for number of rows for(row=1;row<=n;row++)                       // For number of rows { for(col=n;col>=row;col--)                //For number of columns { printf("*")...
